HS Code for Fiberglass yarn

Fiberglass yarn is classified under HS code 7019.13. This classification applies to glass fibers that have been processed into yarns or slivers. Unlike rovings, fiberglass yarns typically possess a twist, which provides the structural integrity needed for weaving or knitting into fabrics. The Harmonized System distinguishes between different forms of glass fiber based on their mechanical processing. Heading 7019 covers the broad category, while 7019.13 specifically targets "yarns and slivers." Slivers are untwisted strands of glass fibers, often shorter than continuous rovings, while yarns are the twisted counterparts. This code is essential for textile manufacturers who import glass fiber for the production of fire-resistant clothing, industrial curtains, or electronic-grade glass cloth. The classification is determined by the presence of a twist (measured in turns per meter) and the linear density of the yarn. Customs documentation often requires the specification of the filament diameter and the number of plies to confirm the 7019.13 designation. This code ensures that the material is recognized as a textile-grade input rather than a bulk reinforcement material.

Common Misclassification

The most frequent misclassification is with fiberglass rovings under 7019.12. As noted, the presence of a twist is the deciding factor. Another common error is classifying glass yarn under 7019.11, which is for chopped strands. If the yarn has already been woven into a mesh or fabric, it should be classified under 7019.61 through 7019.69. Additionally, if the yarn is coated with plastic to the extent that it takes on the character of a plastic article, it might be challenged under Chapter 39, though 7019.13 remains the standard for most industrial glass yarns.

FAQ

What is the HS code for fiberglass yarn?

The correct HS code for fiberglass yarn and slivers is 7019.13.

Can fiberglass yarn be used for 3D printing?

While glass fibers are used in 3D printing filaments, the yarn itself (7019.13) is a textile input. If it is embedded in a plastic filament, it is usually classified under Chapter 39.
